Title: Burner
Inventor: OKIHARA TETSUYA
IPC: F23L3/00
Filed: 1980-08-04
Abstract: PURPOSE: To obtain an effective operation of the burner under a constant extra air coefficient over the entire load range, particularly in a low load range by a structure wherein a sleeve provided in a burner casing is divided into two parts, each connected to an independent air passage and the air passage is equipped with a damper.  
     CONSTITUTION: The sleeve provided in the burner casing 1 is divided into two parts, a primary sleeve 2 and a secondary sleeve 3; the primary sleeve 2 having a primary throat 5 and inserted therethrough with a sprayer body 10 which is provided with a primary swirler 11 and an atomizer 12 positioned within the primary throat 5, and the secondary sleeve 3 inserted therethrough with the primary sleeve 2. These primary and secondary sleeves are connected respectively to independent air passages a and b and equipped respectively with a primary damper 8 and secondary dampers 9a and 9b. Within a low load range of combustion in which a boiler load is less than 50%, a primary combustion air is supplied into the primary throat 5 via the primary damper 8, air passage a and primary sleeve 2. In this instance, flowing speed of the air is maintained by the primary swirler 11 and primary throat 5. The fuel is thus effectively mixed with the primary air to be burned with a certain amount of extra air even at low load.

Title: Pid control method
Inventor: KOMORI KUNIHARU
IPC: G05B11/42
Filed: 1990-04-25
Abstract: PURPOSE:To settle a controlled variable in a short time without causing overshoot by calculating a bias automatically by an apporximate expression, and controlling a controlled system according to output rate calculated by considering this bias the initial value of an integration correction term.. CONSTITUTION:A positive direction bias arithmetic part 5 and a negative direc tion bias arithmetic part 5 calculate respectively integration correction values a positive direction PID arithmetic part 2 and a negative direction PID arithme tic part 4 ought to generate when the controlled variable (temperature) is settled at a target value, and output them respectively as a positive direction bias A<+> and a negative direction bias A<->. An adder 6 adds a positive direction PID calculated value and the positive direction bias A<+>, and generates positive direc tion output rate y<+>, and the adder 7 adds a negative direction PID calculated value and the negative direction bias A<->, and generates negative direction output rate y<->. The controlled system 8 is controlled according to the positive direction output rate y<+> and the negative direction output rate y<->, and a detector 9 detects the controlled variable the controlled system 8 outputs, and outputs a detected value Xn. Thus, the controlled system can be settled in a short time without causing the overshoot or a dead zone.

Abstract: PURPOSE:To obtain a horizontal synchronizing signal in an excellent way from a composite synchronizing signal whose horizontal frequency differs largely by controlling the current source of an equalizing pulse eliminating circuit in response to the horizontal frequency of the composite synchronizing signal. CONSTITUTION:A capacitive load C1 is inserted between 1st and 2nd time constant terminals T1, T2 of a 1st monostable multivibrator 3 being a component of an equalizing pulse eliminating circuit 11.

Title: Method for holding optical fiber under aligned condition
Inventor: NAKAO MASAO
IPC: B65H54/02
Filed: 1982-06-25
Abstract: PURPOSE:To automatically hold optical fibers under a condition where they are aligned to a desired form, by putting optical fibers between warps which are warped and arranged in parallel with each other, and then, by performing weaving by crossing the warps and woofs each other. CONSTITUTION:After a cloth 7 having a required length is woven, the projected part 13 of an optical fiber 11 is projected over warps 2 through the warps 2 by actuating an optical fiber transferring mechanism 12 under a condition where a reed 6 is at the right side position. After the optical fiber 11 is fixed by a fixing tool 18, a holding tool is lowered and stopped at a position just below the projected part 13. At the same time, woofs 5 are beaten by actuating a reed sliding mechanism 20 and the holding tool 16 is again raised after cutting the optical fiber 11 with a cutter 19, and then, the projected part 13 is projected over the warps 2. This operation is repeated and the optical fibers 11 are held between the warps 2 and woofs 5 under an aligned condition. Therefore, by changing the operation of the transferring mechanism 12, optical fibers can be held automatically under a condition where they are aligned to a desired form.

Title: Method for detecting abnormal low temperature and abnormal low temperature detector utilizing the same
Inventor: IGAWA KOJI
IPC: G01K11/12
Filed: 1990-04-26
Abstract: PURPOSE:To highly accurately detect a low temperature part generated due to breakage by comparing the attenuation rate of a signal in a loss part with a previously stored attenuation rate at the time of generating a loss in a signal less than a threshold at a certain distance from a light source. CONSTITUTION:A distribution type fiber temperature sensor measures the temperature distribution of an optical fiber to be measured which is obtained by a signal processing part 17. While taking notice of a sudden loss part in the temperature distribution, if the loss is less than the threshold, no generation of abnormal low temperature is decided. When the loss is more than the threshold, the generation of abnormal low temperature is decided and the succeeding processing is executed. The attenuation rate (dB/km) of the signal in the loss part is calculated. The calculated attenuation rate is compared with the previously the stored attenuation rate of the measured optical fiber at each temperature to find out the temperature of the loss part. Consequently, the temperature and position of the low temperature part generated due to the damage of a tank for liquefied gas or the like or a pipeline can be accurately detected without using a specific optical fiber with less loss in a low temperature.
